failed breakfast bars

I've been eating a lot of granola bars from Trader Joe's lately (whole grain, healthy snacks help stave off both hunger and headaches) but decided I could do better by making my own... so I dug out Nigella Lawson's recipe for breakfast bars (from her Good Food Fast cookbook; you can also read a modified recipe on the Sweet Kitchen blog) and had a go at it. I think I must've played with too many variables, though, because they turned out less of a bar and more of a crumbly bread pudding/granola mixture, some parts being soggy and other parts crunchy.

I didn't have any condensed milk on hand, so I substituted a can of coconut milk (not really the same thing, I found out later), then left out the coconut flakes (which I didn't have either), and instead of dried cranberries I used raisins, and instead of unsalted peanuts and assorted seeds I added slightly salted cashews. I did think to toss in a little ground cinnamon, which would've been a nice touch if only the texture had come out properly.

I'm still getting used to the new toaster-sized convection oven, so I think I took it out a little early. Not much else could have gone wrong, but at least it's not burnt, right? It's actually still munchable, but just not as appealing as a good solid cookie bar would've been.

I'll have to pick up some condensed milk from the store and try it again, one of these days. Does anyone else have any good recipes? These raspberry bars and these blueberry bars also sound great.
